Wow, this is great. You've painted the tense, delicate relationships between the three of them so wonderfully. I really like how you approached their deaths and what it's like after. As Lily says, it's not easy, yet the way they slip into it feels very natural and rings true with how the afterlife is presented in the books. A bit dreamlike, yet also matter-of-fact and no frills. They go onward in this new existence, and can experience each other in a way they perhaps never could have in life.
Color me impressed. Thank you for this.
